Just the last couple of mornings I have had a "sqeek" under the hood while warming up. I have not been able to find the source but I am now quite concerned the source has been identified. I may be able to come up with the correct bearing but if I have to replace it I expect a refund from LET. As my forum history shows LETs' 185mm pulley set up has all ready cost me $600.00 out of pocket, for tow and belt replacement costs. I don't think I should have to invest anymore in their product.
